@burcinc-- I'm not an expert on Chinese cuisine. I'm sure there's someone here who is more experienced and can give you better information.
However, I was in Beijing for a short while and could not, for the life of me, find lo mein noodles at the store. It could be that it was there and I missed it, or it's called something else, I'm not sure. But I agree that food in China is not exactly the same a Chinese food in America, which is more like Americanized version of Chinese dishes. That's understandable though because the food has to suit American tastes.
I did find that food in China was more flavorful than the Chinese food we get here. But you can always solve that by looking up recipes and making authentic Chinese dishes at home.
